Roof valleys are critical channels where two roof slopes meet, and in San Francisco's damp climate, they are a prime spot for leaks. Our comprehensive roof and attic inspection specifically examines the valley flashing for wear, corrosion, or improper sealing. We also check the attic for signs of moisture intrusion, like water stains or mold, which often point back to a valley issue. By identifying weak points early, we can perform targeted repairs or recommend protective measures like enhanced waterproofing to prevent a small problem from becoming major water damage.

Poor roof ventilation is a common issue in San Francisco, leading to trapped heat, moisture buildup, and higher energy bills. We address this through a multi-step approach. First, our attic inspection assesses your current ventilation system. We then provide solutions like installing ridge or soffit vents to promote proper airflow, which is crucial for moisture control. Often, we pair this with gutter services—cleaning existing ones or installing new gutters with proper downspouts—to ensure water is effectively channeled away from your roof and foundation, working in tandem with your improved ventilation system.

This is a key decision. Re-roofing involves adding a new layer of shingles over the existing one, which can be a cost-effective solution for some homes. However, if the underlying issue is chronic moisture or ventilation problems that have compromised the roof deck, a full roof replacement is the durable, long-term solution. For San Francisco homes, we often recommend replacement when dealing with persistent leaks, as it allows us to install modern waterproofing underlayments, correct any structural ventilation issues, and ensure a completely sound base. Our inspection will determine the best course to permanently resolve the moisture control problem.
